AFT fan noise radiating from the bypass exhaust duct is usually attenuated by acoustic lining along the inside of the duct only. The unconventional treatment of the afterbody, recently proposed by Tester et al. [1–3] has been shown to provide an additional potential of damping of the order of 1 to 4 dB. This is remarkable, given the fact that most of the sound is supposed to radiate away from, ...

Histological and histochemical studies on the pancreas of goose (Anser albifrons) were carried out using special staining and light microscope. The pancreas in goose is serous tubuloacinar gland having exocrine and endocrine part. Smooth muscle fibres were absent in capsule of pancreas. Acinar cells have bizonal shape. Intralobular ducts, Interlobular and main excretory ducts were present withi...

In a 15 year prospective study of endoscopic surveillance of columnar lined oesophagus, 102 patients with a mean follow up of 54 (12.5) months and total follow up of 462 years have been evaluated. Of all the sets of biopsies taken, 59 in 21 patients were found to exhibit dysplasia or carcinoma. Four male patients had carcinoma of the oesophagus, indicating a 30 times increased risk of developme...

RNA has been proposed to be a component of an underlying nuclear matrix. Hall et al. show that noncoding, repetitive RNAs, some derived from LINE1 elements, stably associate with interphase chromosomes and copurify with nuclear scaffold, indicating that RNAs might impact interphase chromosome architecture.
